Seems like this is configuring the 'default' options and returning a reference
to it (which you later use to modify the options), is that correct?

If so, should this instead return a pointer (to denote that it's mutable)?
And what about calling this MakeNativeApplicationOptionsForUrl?

feel free to ignore tho

     const GURL& url) {
   DCHECK(!url.has_query());  // Precondition.
   // Apply mappings and resolution to get the resolved URL.
   GURL resolved_url =
       delegate_->ResolveMojoURL(delegate_->ResolveMappings(url));
-  DCHECK(!resolved_url.has_query());  // Still shouldn't have query.
   // TODO(vtl): We should probably also remove/disregard the query string (and
   // maybe canonicalize in other ways).
-  DVLOG(2) << "Storing native options for resolved URL " << resolved_url
-           << " (original URL " << url << ")";
-  url_to_native_options_[resolved_url] = options;

+  return url_to_native_options_[resolved_url];
 }
